double slam
n.— «There obviously was a lot of bonding time in Welch’s quest to get his granddaughter’s wild turkey “grand slam,” as it’s known, on video.…Luckett has accomplished…the grand slam twice, along with a double slam (killing two of each bird) and the royal slam. For the grand slam, a hunter must kill an Osceola, Eastern, Rio Grande and Merriam. The royal slam includes the Gould sub-species, native to Mexico.» —“Turkey hunter, 10, bags first grand slam” by Larry Rea Commercial Appeal (Memphis, Tenn.) Oct. 27, 2005.
